From ce62350d8f5a619c9ce754caeb1e33224e0cce56 Mon Sep 17 00:00:00 2001 From: Xavi Drudis Ferran Date: Mon, 28 Feb 2011 03:19:17 +0000 Subject: Improving BKDG implementation of P-states, CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. Add to init_fidvid_stage2 some step mentioned in BKDG 2.4.2.7 that was missing . Some lines are dead code now, but may handy if one day we support revison E CPUs.
